GUARD FOR WATER-GAG ES.

SPECIFICATION forming part of Letters Patent No. 668,325, dated February19, 1901. Application filed August 6, 1900. Serial No. 25,970. (Nomodel.)

To all whom 25 may concern:

Be it known that we, WILLIAM H. BROOKS and HERMAN C. FISCHER, residentsof Cleveland, in the county of Cuyahoga and State of Ohio, have inventedcertain new and useful Improvements `in Guards for Water-Gages; and wedo hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it pertains to make and use the same.

Our invention relates to improvements in guards for water-gages that areemployed in connection with and indicate the depth of water in asteam-boiler and that are more especially serviceable upon a locomotive.

The primary object of this invention is to provide a gage of thecharacter indicated that has not only the safety and reliabilityrequired to positively avoid injury to the engineer or reman havingcharge of the locomotive upon which the gage is used resulting fromflying pieces of glass or escaping steam or hot water upon a breakage ofthe 'glass of the gage, but that comprises a guard having three windowsarranged at suitable intervals around the guard, one facing theengineers position, another facing the firemans position, and anotherfacing the burner of a lamp with which the guard is provided, so thatthe glass of the gage and its contents are capable of being adequatelyilluminated at all times, in the night-time as well as in the day-time,and the engineer and the lireman are able to observe the height of thewater in the gage with facility at all times.

With this object in View and to the end of realizing other advantageshereinafter appearing the invention consists in certain features ofconstruction and combinations of parts hereinafter described, andpointed out in the claims.

In the accompanying drawings, Figure I is a top plan of the gageprovided with a lampbearing guard embodying our-invention. Fig. II is aside elevation, largely in central vertical section, on line II II, Fig.I. Fig. III is a side elevation, largely incentral vertical section, online III III, Fig. I, looking toward the lamp of the guard. Fig. IV is atop plan, in horizontal section, on line IV IV, Fig. Il.

Referring to the drawings, a designates the glass tube or glass of thegage, which glass is provided with an upper head b and a lower head c,to which are connected different pipes, respectively, leading from thewater-space and steam-space, respectively, of the boiler (not shown) andcommunicating in the usual manner with the lower end and upper end,respectively, of the chamber of the glass a.

The guard for the glass a consists of a case or sheath composed in themain of sheet metal and surrounding the gage and extending from top tobottom of the gage and preferably a short distance above and below thegage. The said case is open at its upper and lower ends and is larger inend elevation or transverse section than the gage, so as to form anannular space within the guard around the gage, which space accommodatesthe escape of the hot water and steam from the lower end and upper end,respectively, of the guard when the glass of the gage becomes broken.The said case consists, preferably, of two sections c and c, embracingthe gage and hinged together vertically and longitudinally of the gageat one side of the gage, so as to render the said sections e and ccapable `of being swung in a horizontal plane upon the said hingeconnection toward and from each other. One of the sections c extendsabout two-thirds of the distance around the gage, and the other sectionc extends from the said hinge connection somewhat more than theremaining onethird of the distance around the gage, as shown Figs. I andIV. Each section e is provided upon its inner surface with two jaws e2and e2, arranged adjacent to the upper head and lower head,respectively, of the gage and adapted to close against the adjacentgagehead in the closed position of the sections e. The hinge connectionbetween the sections e and c is composed, preferably, of one or moresuitably applied spring hinges c', Whose springs e4 act to retain thesaid sections in their closed position. It will be observed, therefore,that the gage has its heads b and c clutched by and between the jaws e2of the `sections e, and the springs e4 act to maintain the said jaws intheir operative position, and hence act to retain or hold the guard uponthe gage.

The smaller of the two sections c and c when thegage is in use upon alocomotive faces the section e.

engineers position and is providedwith a slot e5, that extends up anddown or longitudinally of the said section and is closed by asight-glass 7c, held in position in any approved manner. The glass a ofthe gage is therefore visible to the' engineer' from the engineers lseat through the window-forming sight-glass lr'.

The largerof the two sections e and c, that, as already indicated,extends about twothirds of the distance around the gage, is providedwith two slots e and e7, extending up and down or longitudinally of thesaid section. The slot e7 is arranged directly opposite the slot e5. Theslot c6 is arranged directly opposite the hinges e and centrally betweenthe slots e5 and e7. The slot e6 is covered by a sight-glass l, that isheld in position in any approved manner. The glass 0, of the gage istherefore visible to the fireman through the sight-glass l. The slot e7is covered by a sight-glass m, that transmits into the chamber or space-surrounding the glass of the gage the rays of light radiating from theluminous body or member of a lamp with which the guard is provided, aswill hereinafter more fully appear. It will be observed, therefore, thatthe larger of the two sections e and e of the guard has a window-formingsight-glass Z, arranged directly opposite the hinges e, and has awindow-forming sightglass m, arranged directly opposite thewindow-forming sight-glass la of the companion section e. Thesight-glassmis arranged within a holder n, constructed in any approvedmanner and rigid with the connected guard- The holder n is provided withtwo slideways n and ln','arranged vertically and a suitable distanceapart at the outer side of the sight-glass m.

Each slideway 'n' is engaged by a verticallyarranged slide o', formedupon or rigid with an upright tubular guard o, that surrounds the burnerp, with which the lamp p, that is suitably supported from the lower endof the said guard o, is provided. .The guard 0 prevents the ame frombeing extinguished by the wind. The guard o at its lower end (see Fig.II) is provided with lateral perforations o2, that form air-inlets foradmitting air to the burner of the lamp. The guard o (see Fig. Il) isslotted vertically, as at 05, directly opposite the sight-glass m,between the burner of the lamp and the said sight-glass, and the slot 0Sis closed by a suitably-applied sight-glass r, that is held in place inany approved manner. The window-forming sight-glass r of the lampguardis arranged, therefore, directly opposite the sight-glass m, so that therays of light from the burners flame are transmitted to the chambersurrounding the glass a, of the gage.

The lamp-guard o, directly opposite itssight-glassr and adjacent to theburner of the lamp, is provided with an aperture o4, that is closed by asuitably-applied slide t, that extends between and engages twoverticallyarranged slideways oand 05, formed upon the lamp-guard asuitable distance apart. The slide 2f is shiftable upwardly, and theaperture o4 when the slide is thus shifted affords access to thelamp-burner. t

The lamp-guard 0 has its upper portion conical and is open at the upperand smaller end of its said conical end portion. ternal surface of thelamp-guard o and its slide are made, preferably, of sheet metal that ishighly polished, and consequently the lamp-guards inner surfaces,(including the inner surface of the slide 15,) that are arrangedopposite to the sight-glass r, form a reflector for reecting rays oflight through the sightglasses r and m into the chamber or spacesurrounding the glass a of the gage.

The guard-slides o and the connected lamp- I guard are removableupwardly from the slideways n', and a stop-forming shelf or ange or lugn2 is formed upon the sight-glass holder n and arranged as required toform a seat for the lamp and lamp-guard.

1.- A water-gage guard comprising a case composed of two sections havingthe dimensions required to render them capable, when they are closetogether, of surrounding'the gage and fo'rming a space between theexterior of the gage and the inner surfaces of the said sections, meansfor holding the case-sections upon the gage, a slot e5 formed in andextending up and down one of the case-sections, a sight-glass k coveringthe said slot, two slots e6 and e7 formed in and extending up and downthe other case-section and the sight-glasses Zand m covering the dierentlast-men tioned slots, respectively, and a lamp removably attached tothe lastmentioned case-section and arranged as required to illuminatethe aforesaid space through one of the last-mentioned sight-glasses.

2., A water-gage guard comprising the following: a case composed of twosections e and e hinged together, as at e', and having the dimensionsrequired to render one of them capable of extending around the gagefarther than the other, and, consequently, being the largest section;means for holding the casesections upon the gage; the slot e5 formed inthe smaller case-section; the sight-glass la covering the said slot; theslot e7 formed in the larger case-section directly opposite thesight-glass of the smaller case-section; the slot e6 formed in thelarger case-section directly opposite the hinge connection between thetwo case-sections and the sight-glass Z for covering the last-mentionedslot, and a lamp attached to the larger case-,section and arranged atthe outer side of the first-mentioned slot of the said case-section, allarranged and operatingsubstantially as shown, lfor the purposespecified.

3. A water-gage guard comprising the following: a case composed of twosections e and e hinged together, as at e', and having the dimensionsrequired to render one of them capable of extending around the gagefarther IOC IIC
